Penryn is current 65 nm chips moved to 45 nm technology. They call these odd year improvements the
"tick" as compared with the even year improvements which are called the "tock". The Penryn chips were
being made in September for planned shipments on November 12, 2007. In Penryn chip if one core is
not being used, it can shift the operating core to higher frequency in order to utilize the thermal budget
of the whole chip.
2008 Nehalem on 45 nm technology. These "tock" improvements take advantage of the improved
transistor density provided in odd years to cram more processors and capability onto the chip.
Obviously the defect rate goes down as the process is improved. This allows their making of larger
chips with more functions. Will deliver 8 core dies each core will be double threaded so that the chip will
be capable of processing 16 simultaneous threads. This 8 core Nehalem chip is now running in
prototype and has 731 million transistors per chip. The development team is in Oregon, USA. They
also have a "quickpath" technology in order to speed up communications between CPUs. Quickpath is a
serial bus which engages in full-channel training to optimize speed under given conditions. They are
adding new instructions, some of which are for video encoding and decoding.
The older technology, front side bus, can multitask 60 processors in logical mode and this will be
increased to 1 million processors with quickpath. It is none too soon given the fact that 8 processor
chips will be manufactured next year.
